Dynasylan® 1401

• In the presence of water, the methoxy groups of Dynasylan® 1401 hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates.
• The organophilic diamino group of Dynasylan® 1401 can react with a suitable polymer.
• The hydrolysis of Dynasylan® 1401 takes place autocatalytically.
• The pH of the hydrolysate is about 10-11. Dynasylan® 1401 may be used with such polymers as phenolic, furan resins and silicones.
• Dynasylan® 1401 can undergo reactions with ketones or ester solvents.
• The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates or carbamates, respectively.
• Product modifications are possible through co-condensation with polysiloxanes (textile auxiliaries).

Dynasylan® 1401 can be used in many applications.

Examples are:

• additive for cold-curing phenolic and furan foundry resins to improve the flexural strength of the sand-resin composites while maintaining the shelf life of the resin over long periods.
• starting material in the synthesis of amino-functional silicones.
• additive to phenolic resin binders for mineral fiber insulating materials.
• primer for additive to sealants and adhesives.
• additive and/or primer for improving the adhesion of paints and coatings to the substrate.

Important product effects that can be achieved through the use of Dynasylan® 1401 include:

• improved mechanical properties, e.g. strength, impact strength and modulus of elasticity.
• improved moisture and corrosion resistance.
• improved electrical properties, e.g. dielectric constant, volume resistivity.

Dynasylan® 1401 can also Improve processing properties such as

• adhesion.

Dynasylan® 1401 is supplied in 25 kg pails or in 200 kg drums.
